  • Handling apostrophes, php and pgsql

    - by running4surival
    For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

  • Organize array in PHP from mysql

    - by Matthew Carter
    Hi i have a social networking website. what i want it to do is pull out my friends status updates. basically what it does is i have a mysql query that pulls out all of my friends and in that while loop there is another mysql query that pulls out the status's from my friends. i want it to be in order of date but since its one while loop in another what it does is pull out all status's from friend 1 then 2 then 3 and not in order by date. i even tried ORDER BY DATE but that just ordered it by date within the friend.. my thought is that i could putt it all in an array and friends is one thing and the values is the stats. then just sort by values would this work and how could i do it. THANKS SO MUCH

  • PHP - Get dates of next 5 weekdays?

    - by Dan
    I'm trying to create an array of the next 5 working week days (Monday - Friday, excluding today). I know the working week varies around the world but this is not important for what I am trying to do. So, for example, if today is a Wednesday, I want the dates for Thursday and Friday of the current week and Monday, Tuesday and Wednesday of the following week. I thought this would work: $dates = array(); for ($i = 1; $ < 6; $i ++) { $dates[] = date('Y-m-d', strtotime('+ '.$i.' weekday')); } But for today, it is giving me: Monday 1st Tuesday 2nd Wednesday 3rd Thursday 4th Sunday 7th! Any advice appreciated. Thanks

  • PHP DOMElement, replacing text of a node

    - by waitinforatrain
    I have a HTML node like so: <b>Bold text</b> A variable $el contains a DOMElement reference to the text of that HTML node ("Bold text"), got from the XPath expression //b/text() I want to change the element to <b><span>Bold Text</span></b> So I tried: $span = $doc->createElement('span', "Bold Text"); $el->parentNode->replaceChild($span,, $el) which fails because parentNode is null. So, as a test, I tried: $el-insertBefore($span, $el); which throws no errors but produces no change in the output. Any thoughts?

  • PHP ingore case sensitivity when comparing array values

    - by dan.codes
    I have to modify some code in a application I am working on that is using the array_diff($array1,$array2) method. The problem I am having is it is case sensitive and I need to have it return the correct value if the array values match even if the case is different. I don't want to change the case to lowercase because I need the value returned to keep its case. I'm a little confused as the best method to do this.

  • php: simplexml exception retry

    - by exceptionhandlingnoob
    I am querying an API using SimpleXML which will occasionally fail for reasons unknown. I would like to have the script retry up to 5 times. How can I do this? I assume it has something to do with wrapping the object in a try/catch, but I'm not very experienced with this -- have tried to read the manual on exception handling but am still at a loss. Thanks for any help :) // set up xml handler $xmlstr = file_get_contents($request); $xml = new SimpleXMLElement($xmlstr); Here is the error message I am receiving: [function.file-get-contents]: failed to open stream: HTTP request failed!

  • Basic security, PHP mySQl

    - by yuudachi
    So I am making a basic log-in page. I have a good idea of what to do, but I'm still unsure of some things. I have a database full of students and a password column of course. I know I'm going to use md5 encryption in that column. The student enters their e-mail and student ID, and they get e-mailed a password if correct. But, where do I create the password? Do I have to manually add the password (which is just a randomly generated string) in mySQL to all the students? And I am suppose to send the password to the student; how will I know what to send the student if the password is encrypted? I was thinking about generating the password when the student first enters their e-mail and student ID. They get an e-mail of the random string, and at the same time, I add the same random string to the database, encrypted. Is that how it's suppose to work though? And it feels unsafe doing that all on the same page. Sorry for the long-winded, newbish question. I find this all facisnating at the same time as well (AES and RSA encryption :O)

  • Confused by this PHP Exception try..catch nesting

    - by Domenic
    Hello. I'm confused by the following code: class MyException extends Exception {} class AnotherException extends MyException {} class Foo { public function something() { print "throwing AnotherException\n"; throw new AnotherException(); } public function somethingElse() { print "throwing MyException\n"; throw new MyException(); } } $a = new Foo(); try { try { $a->something(); } catch(AnotherException $e) { print "caught AnotherException\n"; $a->somethingElse(); } catch(MyException $e) { print "caught MyException\n"; } } catch(Exception $e) { print "caught Exception\n"; } I would expect this to output: throwing AnotherException caught AnotherException throwing MyException caught MyException But instead it outputs: throwing AnotherException caught AnotherException throwing MyException caught Exception Could anyone explain why it "skips over" catch(MyException $e) ? Thanks.

  • PHP registration script: verifying and telling the user what went wrong

    - by Maxime
    Hi, I'm building a registration script and I want to insert the user's input (username, mail) ONLY if it's not already in the database. What I usually do in such cases is a request to see if something's already there, something like: "SELECT * FROM things WHERE thing_name = '$treated_user_input'". I have two fields that need to be unique this time though. Is there a way to do only one SELECT request and still be able to tell the user exactly what field went wrong? Or do I have to do one request per unique field? Thanks for your answers.
